AT3 Tactical White M-LOK Receiver Set – BLEM

We used this set for the photos on this page – there’s a few scratches around the buffer threads and takedown pins.

Start a new Bright White AR-15 build with this limited run from AT3 Tactical! This AT-15 M-LOK Receiver set includes an AT-15 Lower with Enhanced Trigger Guard, Billet Upper, and 15 Inch SPEAR M-LOK Handguard, all finished in Bright White H-140 Cerakote.

Since this is a big bundle, we knock 10% off the total price of every part, so you’re saving money right off the bat. Plus, this set is packed with features to improve performance and customization. The SPEAR M-LOK handguard comes with a 5-slot rail adapter and tons of M-LOK slots, with a 7075-T6 aluminum barrel nut for tough, lightweight performance. The lower receiver also has a deep magwell flare, making reloads easier and faster to pull off.

To get your rifle together, start with a lower parts kit, a buffer kit, a barrel of your choice, bolt carrier group, and charging handle. And as always, the pistol grip and stock that fits you best. If you’re looking for our standard colors, we have the same M-LOK Receiver Set with more options for handguard length.

FAQ

Is this lower Mil-Spec?

The AT-15 uses 7075-T6 aluminum construction, and is available in a type 3 hardcoat anodized finish, which are mil-spec. The AT-15 also accepts all mil-spec AR-15 components. Most triggers, pistol grips, lower parts, buffer tubes, and upper receivers will have no issue fitting into this receiver. With the Cerakote options, the thickness of finish in some areas may make the fit a bit tighter.

What is Cerakote?

Cerakote is a ceramic paint and adheres to polymer and metal very well. Since the the lowers are painted, some wear marks may be seen on areas of heavy use. AT3 doesn’t warranty against Cerakote inconsistencies or the wearing of coatings. Our parts are Cerakoted using the official Cerakote colors.
